Abstract:
The refined wheat flour was mixed with different types of wheat starch in different addition levels, their microstructure, chemical bonds in the dough and baking characteristics of 0-8 weeks frozen dough bread were studied. With the increase of A-Type starch granules and whole wheat starch, the pores of gluten network first decreased and then increased. Conversely, an increase in B-Type starch granules consistently reduced gluten network porosity. With the increase of whole wheat starch, the content of free sulfhydryl group and hydrophobic interaction decreased gradually. Minimal additions of B-Type granules were found to enhance the specific volume of fresh bread, whereas increased quantities improved the specific volume of frozen dough bread. The addition of a small quantity of A- or B-Type granules enhances the freezing stability of bread. This study provides effective information for elucidating the effects of wheat starch on the frozen dough and bread properties in protein-starch matrix.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
